The specimen named iodura in the Museum o f M. Heine at Halberstadt is different from the bird so called in
the Museum at Berlin. The former has a glittering crown and light-lilac shining tail-feathers j while the latter has
a dull-coloured crown, and the tail so nearly resembling that o f P . viridigaster that I have no doubt o f its being a
young bird or a female o f that species. On the other hand, I think M. Heine’s bird is a distinct species, and I
have therefore retained it under the term iodura.

The Erythronota are nearly allied to the Pyrrhophana. As in that genus, the sexes are alike in their colouring.
The species are much more circumscribed in their habitat, being almost confined to Venezuela and the countries
immediately adjoining.
The oldest-known species, which I have called antiqua, appears to be subject to much variation in its colour
and markings; but, as I stated in my account o f that species, I have questioned the propriety o f their separation
until we are better acquainted with them.

The birds from Tobago are very much larger than those from Trinidad; and some o f the specimens from
Venezuela have the under tail-coverts wholly chestnut; I should have considered this indicative o f another species,
had I not found a similar variation in specimens from Trinidad.

The 0 . Felicia is admitted by the French Trochilidists to be distinct from O. antiqua, and as such I have kept
i t ; at the same time it is extremely difficult to distinguish one from the other. In size they are as near alike as
possib le; but the former has a bluer tail, and the back and upper surface destitute o f the fiery-red colouring
observable in many specimens, but not in all, o f the O. antiqua; the under tail-coverts, too, are frequently stained
with violet.
I have a specimen o f this bird, presented to me by M. Emile Parzudaki, o f Paris, with the name o f Emile
attached. The bird was killed by him during his visit to South America.

This is a very elegant species,- and quite distinct from every other known Humming-Bird. In its glittering
light-green crown, throat, and chest it looks like a Chlorostilbon; but the form o f its tail and some other characters
ally it to the Erythronota, with which I have provisionally placed it.
The next natural section is that o f Saucerottia, o f which I am acquainted with three species distinguished from
the Erythronota by their larger size, stouter bills, and by their more uniform dark-green colouring. All are
confined to a comparatively limited area—namely, Costa Rica, Veragua, Panama, and the northern parts o f New
Granada.

As the S. Sophia differs from the S . typica in the richer blue colouring o f its upper and under tail-coverts and
tail, so does this species differ from the -S'. Sophia in having the tail and its coverts both above and beneath o f a
still richer and more violet blue. I t is also o f smaller s iz e ; and the green o f its under surface is different from
that o f both, being purer and deeper. The examples in my collection were obtained by M. Warszewicz on the
banks o f the Magdalena.
The bird to which M. Bourcier has given the specific name o f cyani/rons requires separation from the last three
species, as much or more than they do from their predecessors the Erythronota. M. Cabanis’s generic name of
Hemithylaca having been applied to this group as a whole, subsequently to those o f Saucerottia and Erythronota, I
must either place his name in the rank o f a synonym or adopt it for the present species, the only one o f this
particular form.

Somewhat allied to the genera Hemithylaca and Erythronota is the isolated form constituting my genus
Eupherusa. The single species known is a native o f Central America. Contrary to what occurs among the
Erythronota, the sexes differ very considerably in their plumage—a fact o f which I was not aware when my plate
o f the species was executed.
